FOUNTAIN-PEN.

Specification of Letters Patent. Patented Sept. 20 192L Application ledMay 7, 1920. Serial No. 379,560.

To all whom it may concern:

Be it known that I, NORMAN H. A. NELSON, a citizen of the United States,residing at Flint, in the county of Genessee and State ot Michigan, haveinvented certainnew and useful Improvements in Fountain-Pens, of whichthe following is a Speciiication.

This invention relates to self-illing fountain pens and has for itsobject the vproduction of a Simple and efiicient fountain pen whereintwo separate compartments are employed for the purpose ot permitting twodifferent colors of ink to be retained in the pen in the separatecompartments.

Another object of this invention is the production ot a simple andefficient means for facilitating the filling of the pen after the bulbin either compartment has become empty.

Other objects'and advantages of the presen t invention will appearthroughout the following specification and claims.

In the drawing Figure 1 is aside elevation of the pen, and

Fig. 2 is a longitudinal section therethrough. r

.By referring to the drawing,l it will be seen that the pen comprises abody formed of a'piimary section 1 and an auxiliaryvsec-l tion 2. Theprimary section 1 is provided with an extension internally threadedcollar 3 which is threaded upon an externally threaded neck portion/1formed upon the auxiliary section 2 of the vbody of the pen. A pen point5 is carried by the primary section 1 of the body and a pen point 6 iscarried by the auxiliary section 2 of the body. A suitable bulb 7 isassociated with the point 5 for the purpose 'of supplying ink to thepoint 5 and ,a suitable bulb 8 is employed in conjunction with the point6 for supplying ink tol the point 6. Snitable point holder sections 9and 10 are employed for the purpose of supporting the respective penpoints 5 and 6. A protector cap 11 is threaded upon the point holderportion 10 as fshown in Fig. 2 torv the purpose of protecting the point6. A suitable vcap 12 is The compression lever 14 is pivotally mountedupon a supporting pin 15 and this supporting pin 15 is iirmly clampedbetween the primary and auxiliary sections 1 and 2 `of the bodyotthe-pen as clearly shown 'in Fig. 2. The compression lever 14 is alsoprovided with upwardly curved end portions 16 as shown in Fig. 2 andthese upwardly turned end portions 16 are normally seated within thechannels 17 formed in the primary and auxiliary sections 1 and 2 of thebody of the pen. It should be understood that when it is desired toeither lill the bulb 7 or bulb 8, the compression lever 14 may be swungto the desired position thereby raising one end and lowering the otherand upon releasing the compression lever 14 the suction within-the tubewill cause the tube to he filled with ink through the sucking of the inkfrom a bottle or other receptacle up through the pen point into thebulb. The primary and auxiliary sections 1 and 2 of the body of the penare dished or cut away as indicated at 18 located adjacent therespectiveends of the compression lever 14 to facilitate the insertionof the finger nail under the ends of the lcompression lever 14 for thepurpose of swinging the lever to a proper position Vbody of the pen isto provide a means whereby red ink may. be employed in one end ot thepen and blue in the other, or any other desired or suitable color sothat a contrast may be obtained. 'In this way the necessity of employingtwo separate pens may be overcome by retaining the two separate ordistinct colors of ink in the same pen or rather in two separatecompartments, each compartment being located at the opposite end of thebody of the pen. It should be understood that certain detailedmechanical changes may be. employed in connection wit-h the presentinvention without departing from the spirit thereof so long as thesechanges fall within the scope of the appended claims.

I claim 1. A pen of the class described comprising a body having aprimary and auxiliary sec? tion, means for securing said sections together, a pen point carried by each section, a reservoir bulb associatedwith each pen point, and a compression lever pivotally mounted betweensaid sections and adaptedl to coperate with each reservoir bulb for thepurposes of compressing the same.

2. A pen ofthe class described comprising a body formed of a pairofsections, a reservoir bulb mounted within each section, said bodyprovided with an elongated slot formed therein, a pivoted lever inclosedbetween said sections and fitting snugly within said slot, each endofsaid lever being upturned for producing a compression knob adapted toengage a reservoir within the body of the pe and each section providedwith a dished-out portion located near each end of the lever forfacilitating the lifting of the lever and swinging thereof to a desiredposition.

3. A pen of the class described comprising a body formed ofa pluralityof sections, a lever, a supporting pin clamped between said sections andpivotally supporting said lever between said sections, each sectionprovided with a registering slot extending longitudinally thereof forthe purpose of receiving said lever, a pen 4carried by each section, areservoir secured to each pen, and

saidvreservoir adapted to be engaged by the respective ends of saidlever whereby said reservoirs may be compressed for the purpose offacilitating the filling of the reservoirs when said lever is releasedtherefrom.

4. A double ended pen of the class described comprising a plurality ofsections, reservoir bulbs carried by said sections, and

.a compression lever interposed between said lever to permit the leverto be actuated for compressing the reservoir bulbs carried by saidsections.

In testimony whereof I afix my signature in presence of two witnesses.
